Not installing Latest Versions of 6 pods?

After i have installed above pods of Firebase, following pods below are not installed in latest version. I have deintegrated pods, cleaned pod cache, removed podLock.file, then installed again all pods and it still downloads the above versions. i have also uninstalled gem cocoapods, and installed it again and it did not help.

Result of "pod outdated"
The following pod updates are available:

• abseil 0.20190808 -> (unused) (latest version 0.20200225.0)
• BoringSSL-GRPC 0.0.3 -> 0.0.3 (latest version 0.0.7)
• FBSDKCoreKit 6.0.0 -> 6.0.0 (latest version 6.1.0-alpha)
• Google-Mobile-Ads-SDK 7.55.1 -> 7.56.0 (latest version 7.56.0)
• gRPC-C++ 0.0.9 -> 0.0.9 (latest version 1.28.0-pre1)
• gRPC-Core 1.21.0 -> 1.21.0 (latest version 1.28.0-pre1)

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

Examine Podfile.lock to see the dependency requirements. Not all pods allow their dependencies to update to latest.

[Sunrise17]

Is it meaningful to force updating to the latest version of such pods by changing the versions in Podfile.lock?

Example::

• abseil/algorithm (0.20190808):
  • abseil/algorithm/algorithm (= 0.20190808)
  • abseil/algorithm/container (= 0.20190808)
  • abseil/algorithm/algorithm (0.20190808)
  • abseil/algorithm/container (0.20190808):
    • abseil/algorithm/algorithm
    • abseil/base/core_headers
    • abseil/meta/type_traits
  • abseil/base (0.20190808):
    • abseil/base/atomic_hook (= 0.20190808)
    • abseil/base/base (= 0.20190808)
    • abseil/base/base_internal (= 0.20190808)
    • abseil/base/bits (= 0.20190808)
    • abseil/base/config (= 0.20190808)
    • abseil/base/core_headers (= 0.20190808)
    • abseil/base/dynamic_annotations (= 0.20190808)
    • abseil/base/endian (= 0.20190808)
    • abseil/base/log_severity (= 0.20190808)
    • abseil/base/malloc_internal (= 0.20190808)
    • abseil/base/pretty_function (= 0.20190808)
    • abseil/base/spinlock_wait (= 0.20190808)
    • abseil/base/throw_delegate (= 0.20190808)
  • abseil/base/atomic_hook (0.20190808)
  • abseil/base/base (0.20190808):

Firestore depends on exact versions of gRPC-C++ and abseil, so upgrading Firestore will not upgrade the version of those two dependencies (and their sub-dependencies) unless the version is bumped in the Firestore podspec. This includes BoringSSL-GRPC and gRPC-Core.

As for the Facebook dependency, CocoaPods won't install the newest version if it's labeled as an alpha or beta version iirc. You can see the dependency specifier here.

Thanks for your response!

For several of these pods it's not safe to update these pods without testing from us. This is why we pin to specific versions in our podspecs.

Specifically:

• gRPC-C++ 0.0.9:
  • This was a pre-release version expected to break on every update
  • We attempted to upgrade to 1.25 and this uncovered errors
  • gRPC 1.27 up through 1.27.2 failed to publish a cocoapod
  • gRPC 1.27.3--published 2 days ago--is potentially viable; we're testing this now
• abseil 0.20190808
  • needs to be coordinated with gRPC
  • gRPC 1.28 will upgrade to abseil 0.20200225.0
  • We'll evaluate the update once they complete prerelease testing.
• BoringSSL-GRPC 0.0.3
  • This is a version locked dependency of gRPC
  • gRPC-team is responsible for checking compatibility here; I wouldn't second guess them

• gRPC 1.27.3--published 2 days ago--is potentially viable; we're testing this now
• abseil 0.20190808

Are you able to comment on what effects upgrading gRPC could have on the performance / feature-set of Firebase? It seems like a huge leap consisting of several years of development.

The gRPC-C++ 0.0.9 CocoaPod was an experimental packaging of gRPC 1.21 from ~May 2019. Previously only the C core and the Objective-C interface to gRPC were packaged as CocoaPods. The versioning here indicated that the CocoaPod itself was experimental, even though the C++ interface is otherwise widely used and well tested.

I expect there to be no substantial differences in performance and no difference in features at all with the upgrade.
